Ф=angle between the ladder and the ground.
cos Ф= adjacent / hypotenuse
cos Ф=1.5 m / 4 m=0.375
Ф=arccosine 0.375=67.98º≈68º
The angle between the ladder and the ground is 68º
it's a right angled triangle so we will use hypotenuse formula to get the value of x
hypotenuse formula = a² + b² = c²
a = side of the triangle
b = base of traingle
c = hypotenuse ( can be written as h too)
and the formula can also be written as.
c² = a² + b²

Answer:
( 3x + 1 ) ( x - 1)
Step-by-step explanation:
The given fraction is three 'x' to the power of two that is minus from 'x' minus from four. Simplifying that into three 'x' to the power of two. After this three minus 'x' plus four 'x' minus four. By taking common values which is three 'x' multipled by 'x' and minus one adding the entire by the value four which is further multipled by 'x' and minus one. Finally we obtain our answer that is three 'x' plus one multipled the entire by 'x' and minus one.
3x^2-x-4
3x^2
-3x+4x -4
Take common
3x ( x - 1 ) + 4 ( x - 1 )
( 3x + 1 ) ( x - 1)
